I think, I think, I think

I think...
I think I think too much.
Always things on my mind,
Never empty.
And they're never good things
Either-
The bad things,
The sad things,
The confusing things
Are what go round and round.
I wish sometimes
I could just empty my mind,
Wipe it clean
And go back to the beginning.
Start afresh,
And try to avoid the worst things
That life can bring.
Try to stop these thoughts
Keeping me awake at night,
Coming into my mind just when I thought they'd gone
For good.
Always there...
Why won't you go?
